I hooked up to Antminer L3++ last night. One is at 518 mh. The other is at 315 mh. Is there some firmware I can use with the miner to get it up to speed? No idea why it is down so much.
Any ideas why it is so low and any ideas on how to fix it?
check all of the connections to ensure they are connected correctly. Check the power supply use the power supply for the miner thats working and see if that fixes it if it does then you have a bad psu. if not run it with one board connected at a time to see if its a bad board(s). use each board with all the data cables. It’s just a matter of elimination. Could be a psu, board, controlboard or cables.
Have you tried flashing the firmware? you can overclock or underclock using the antminer firmware.
Check your card in the inteface… 315 is too low, you might have bad hashboard. Sounds like only 2 board is working in that L3++. 518, it might be underclocked or you have bad/slow hansboards.
